What the four apps cost

The entry paid plan is the row that matters, because it is where most stores land. Note that the four apps do not price the same thing: the SKU allowance, the number of locations covered and the number of people who can receive an alert all move independently.

Two things stand out. Bee has the most generous free plan by a distance, at five times ours. Stockie gives the most SKUs per dollar on its entry plan. Neither of those is a number we can beat today, so they are the first two paragraphs on the page rather than a footnote at the bottom.

What each one actually does

Prices only mean something next to what they buy. Where a cell says not advertised, the capability is absent from that app's listing, which is not the same as it being absent from the product. Where a feature exists but is gated behind a higher plan, the price of that plan is in the cell.

Slack is where the plan boundaries differ most. Bee and Stockie both put Slack on their Advanced plan, at $11.99 and $9.99. StockAlert advertises Slack without naming a plan. Stockwell posts the daily summary to Slack on the free plan. Instant Slack alerts sit behind the same $4.99 line as instant email, so with us Slack costs exactly what email costs. You connect one channel from Settings and Slack's own dialog picks it, so there is no bot to invite.

The two variant rows are worth reading together, because they are easy to conflate. Every app here alerts on each variant separately, ours included: if the medium runs down while the large sits full, only the medium alerts. What Stockwell cannot do is hold a different number for each variant. The medium and the large share the product's threshold, where the other three let you set each one. On a catalog that runs on sizes selling at very different rates, that is a real difference in their favour.

Which one fits which store

Read this as four honest recommendations rather than a ranking. The apps are genuinely aimed at different stores.

Pick Bee if the free plan has to carry you

Two hundred fifty SKUs for nothing is the best free tier on this list and it is not close. If you are watching a small catalog with no budget, that is the answer. It also has the highest review count of the four, which counts for something on a decision like this.

Pick Stockie if you want the whole inventory system

Purchase orders, suppliers, forecasting and alerts in one app. If you are replacing Stocky in full rather than replacing its low stock report, this is the shape of tool you are looking for. Eight thousand variants on the $4.99 plan is a lot of headroom.

Pick StockAlert if you want reorder points calculated for you

Its entry plan is the priciest here at $7.99 for two hundred variants at one location, so it only makes sense on a short list of products. What it buys you above that is Smart Mode, which sets reorder points from sales history rather than leaving you to work the number out.

Pick Stockwell if you want one job done and evidence it happened

We do alerts. Not purchase orders, not forecasting, not suppliers. Fifteen hundred SKUs and every one of your locations for $4.99, by email or Slack, with a record of every alert we sent and when. That last part is the only row in the table above where every other column is empty. It is the reason we built the app.

Where Stockwell loses

Gathered in one place so you do not have to reverse engineer it from the tables.

• A smaller free plan. Fifty SKUs against Bee's two hundred fifty.
• No reviews yet. The app is new. The others have between one and one hundred twenty five. Weigh that however you weigh it.
• No purchase orders, suppliers or forecasting. We are not a full inventory system for any amount of money.

How to check these numbers yourself

This page was accurate on 3 September 2026 and it will drift, because four companies change their pricing on their own schedule and none of them tells us. Two minutes of checking beats trusting a page written by a competitor.

1. Open the listing. Every app name in the first table links to its own App Store page. Pricing sits under the Pricing tab and it is the only version that counts.
2. Read the plan you would actually buy, not the one at the top of the page. Most of the differences here live one plan down.
3. Count your variants first. Shopify admin gives you the number. Nearly every plan boundary on this page is a SKU count, so knowing yours turns four pricing pages into one number each.
4. Check the location limits if you run more than one. It is the constraint that surprises people, because it is not what any of these apps lead with.

One job, with a record that it happened

Stockwell watches every variant at every location and tells your team by email or Slack before stock reaches zero, then shows you every alert it sent. Free for 50 SKUs. No purchase orders, no forecasting, nothing else to learn.

Get it on the Shopify App Store Free plan covers 50 SKUs with a daily summary. Paid plans add instant alerts and more recipients. No card needed to start.
